Pentasa 2g is a pharmaceutical product containing the active ingredient mesalazine (also known as mesalamine), formulated as prolonged release granules. It is primarily used to treat and manage inflammatory bowel diseases such as ulcerative colitis and Crohn’s disease. The prolonged release formulation ensures that the medication is gradually released throughout the gastrointestinal tract, allowing for targeted anti-inflammatory action in the intestines. Mesalazine works by inhibiting the production of certain chemical substances in the body that cause inflammation, tissue damage, and diarrhea. Pentasa is typically prescribed for both the induction and maintenance of remission in patients with mild to moderate inflammatory bowel conditions.
